Hi everyone,

I recently completed a manual segmentation of a brain tumor from the BraTS dataset using 3D Slicer (12+ hours of refinement and validation). I used:  
• Thresholding  
• Level tracing  
• Smoothing (to anatomical boundaries)  
• Manual correction with Segment Editor  
• Segment Comparison for validation

🧠 The result achieved a Dice score of 1.0 — perfect overlap with the ground truth.  
📦 I’ve packaged everything into a self-contained “Brain Tumor Segmentation Study Kit” for learners:

What’s inside:  
• ✅ .nii and .seg.nrrd files  
• ✅ Full .mrml 3D Slicer scene  
• ✅ Screenshot of segmentation  
• ✅ Evaluation metrics (Dice = 1.0, 0% FP/FN)  
• ✅ BONUS: Editable segmentation template for personal projects

🎯 Ideal for:  
• Students learning segmentation  
• Medical AI beginners  
• Research training  
• Teaching assistants/professors

🔗 Kit is available here (with sample previews):

Would love to hear feedback — and happy to answer any questions about the process, tools, or setup.

Thanks!
